How do tandem solar cells works
WebWhile all solar cells with more than one bandgap are multijunction solar cells, a solar cell with exactly two bandgaps is called a tandem solar cell. Multijunction solar cells that combine semiconductors from columns III and V in the periodic table are called multijunction III-V solar cells. WebPlus, the highly efficient tandem solar cell can be produced at a lower cost than conventional solar cells made of silicon. The solar cell was developed by Professor Dr. Thomas Riedl and his team at the University of Wuppertal, together with researchers from the University of Cologne, the Universities of Potsdam and Tübingen, and the Max ...
